Drafting

if you do this to me, the two of us are going to look like Chesire Cats the whole time and be skidding everywhere... we'll also be going very very slowly.

being able to ride on a wheel is an essential skill in bunch riding or racing, those forum rides where nobody knows how to work together are a perfect example of poor cycling skill. It leaves the slower riders doing extra work, and the faster riders waiting around at every junction.

get yourselves on a club run and learn how to ride in a group.

(or be the solo, hardcore fixie rider, alone and on a mission, courier bag and chip firmly strapped on shoulder)

i draft things all the time. generally not other cyclist (unless i see a carbon roadie), but bus' are very useful to draft and then eventually slingshot round.

i did that on my way home this evening and timed it poorly and had to sprint a lot faster than normal to cut him up just before i got pushed into the central reservation.
